VIPA 300 v series PLC in the application of the stainless steel continuous annealing line project

1 introduction in the metallurgical industry control of the extensive use of Siemens products. My company in metallurgical projects, and gradually introduced and Siemens product is fully compatible with German VIPA, cost-effective products, has achieved good results, also improve my company competitiveness in the undertaking projects. 2 system structure in a stainless steel continuous annealing line project, we use the German company VIPA 300 v series control system, its main configuration as follows: 1) 315-1 VIPA PLC 2 dp01 as the central processing unit (CPU); 2) 4 VIPA 200 v as a remote station, one of the remote station also put a piece of VIPA CP240 - RS485 communication interface module 2, and 4 pieces of temperature control table RKC waalwijk communication; 3) 16 sets of Italy EEI dc transmission system with Profibus DP communication company; 4) (2) inverter with Profibus DP communication; 5) 1 do touch-screen operator station; 6) Station 1 industrial control engineers. System block diagram is shown in figure 1. After less than half a month at the scene debugging the system, it has entered the stage of normal production. The whole control system from the controller to remote station USES the VIPA products of the company. 2. 1 master station: choose the VIPA 315 - 2 dp01 controller, in addition to hook up the VIPA 300 series of switch input module and VIPA 321 - 1 bl00 VIPA 322 - two piece, output module 1 bl00 three pieces, analog input module VIPA 331 - 7 kb01 piece. The arrangement is shown in figure 2. 2. Four remote station 2: choose VIPA 253 - 1 dp01 as interface module, choose the corresponding VIPA 200 v series of I/O modules in different site. Each station can plug up to 32 VIPA 200 v I/O module. The configuration diagram is shown in figure 3. Its usage and Siemens ET200M is similar, but want to install VIPA company providing special GSD file to be used for Profibus configuration, each remote station can set up to 32 module, function module in the former in principle, switch module in the back. 2. 16 sets of 3 Italian EEI dc transmission device: 16 sets by our company and Italian EEI joint venture production of dc speed regulator (83 b 585 x) Through the matching of the Profibus DP communication board R123 VIPA 315 - 2 dp01 bring on DP bus interface, realize the communication of each motor control. 2. 4 2 sets of Siemens MM440 frequency converter: 2 sets of Siemens MM440 frequency converter and the EEI dc speed regulator to hang together in the same DP bus, can through the communication set parameters and read the frequency data. 2. 5 do touch-screen operator station 1:1 Taiwan EVIEW company's color touchscreen MT510T as an operator interface, with the VIPA 315 - by MPI cable 2 dp01 communication, can be in the site control cabinet on the status of the monitoring system, and can set some control parameters. 2. 6 1 industrial engineer station: 1 research China industrial computer as the engineer station, installation of Siemens WINCC configuration software as the man-machine interface, and VIPA 315 - by MPI cable 2 dp01 communications, comprehensive monitoring of the entire unit operation, and make correction in a timely manner. 3 application experience in debugging process of the whole project, the feeling and used Siemens controller is almost no difference. Using VIPA PLC controller, a company's programming platform using Siemens STEP7 V5. More than 2 versions, and Siemens PLC programming method. Hang DP bus for VIPA remote module, to install the VIPA GSD file provided by the company, its usage and Siemens remote station is similar. Each remote interface up to 32 VIPA 200 v module. Therefore, its extension ability is very strong, high cost performance. VIPA PLC with a MP2I interface, its biggest advantage is to use green cable ( RS232 cable) Programmable, don't use MPI adapter. This creates a lot of convenient for debugging maintenance. VIPA PLC internal integration of working memory, running without plus MMC card, but it also with standard MMC card interface, can be used to store programs and data. Thus bring the use of convenience and flexibility.
